Description

Der Erfindung liegt die Erkenntnis zugrunde, daß es für den Betrieb der bekannten, ständig gasdicht verschlossenen alkalischen Akkumulatoren, die ein Elektrodenpaket enthalten, das aus dünnen Elektroden, insbesondere blatt- oder foli>endünnen Sintergerüstelektroden mit den zwischen ungleichpoligen Elektroden liegenden Separatorschichten besteht, von großem Wirkungsvorteil ist, wenn die Schichten mit ihren Oberflächen ohne Pressung aneinanderliegen, um dadurch zu erreichen, daß die Elektrolytflüssigkeit das gesamte Elektroden-Separator-Paket vollkommen durchtränken kann. Hierdurch wird eine besonders beim Überladen des dicht verschlossenen Akkumulators auftretende nachteilige Gasentwicklung vermieden. The invention is based on the knowledge that it is necessary for the operation of the known, permanently sealed gas-tight alkaline accumulators that contain an electrode package made up of thin electrodes, In particular, sheet or film-thin sintered framework electrodes with electrodes of non-homopolarity between them lying separator layers, is of great advantage if the layers with their surfaces lie against one another without pressing, in order to achieve that the electrolyte liquid the can completely soak the entire electrode-separator package. This makes one special when overcharging the tightly sealed accumulator, the disadvantageous development of gas is avoided.

Aus Fertigungserfahrungen ist es bekannt, daß es Schwierigkeiten bereitet, z. B. blatt- oder foliendünne Sintergerüstelektroden immer mit vollkommen gleichmäßiger Dicke herzustellen. Es hat sich gezeigt, daß beim Egalisieren der unter Verwendung dünner Separatoren zusammengesetzten Elektrodenpakete durch Pressen unter hohem Druck leicht Zerstörungen der Separatorschichten entstehen, die zur Bildung von Kurzsc'hlußbrücken in dem Elektrodenpaket führen. Solche Erscheinungen haben sich insbesondere als Auswirkung der Ouelldruckänderungen beim Laden und Entladen des Akkumulators ergeben, wenn das Elektrodenpaket bei seinem Einbau unter dichter Pressung durch das Akkumulatorengehäuse gehalten wird.From manufacturing experience, it is known that it causes difficulties, e.g. B. sheet or film thin Always produce sintered framework electrodes with a completely uniform thickness. It has been shown that when leveling the electrode packets assembled using thin separators Pressing under high pressure easily destroys the separator layers, which leads to the formation of Lead short-circuit bridges in the electrode package. Such phenomena have turned out to be in particular Effects of the changes in the source pressure when charging and discharging the accumulator, if the Electrode package held under tight pressure by the battery housing during its installation will.

Die Konstruktionsgestaltung eines ständig gasdicht verschlossen zu betreibenden alkalischen Akkumulators nach der Erfindung verläßt das vorbekannte Prinzip der Verwendung von dichtgepreßten und durch das Gehäuse unter Pressung gehaltenen Elektroden-Separator-Paketen. Erfindungsgemäß füllt daher das dichtgeschichtete Elektroden-Separator-Paket in Richtung seiner Schichtung den Gehäuseinnenraum nicht vollständig aus, indem die Schichten des Paketes durch Blechstreifen mit federnden Ausbuchtungen, beispielsweise mittels Federzungenblechen, zwischen dem Paket und den in Schichtungsrichtung liegenden Gehäuseinnenwandungen flächendicht aneinanderliegend gehalten werden.The design of an alkaline storage battery that is permanently sealed and operated in a gas-tight manner according to the invention leaves the previously known principle of the use of tightly pressed and Electrode-separator packs held under compression by the housing. According to the invention, the densely layered electrode / separator package therefore fills the interior of the housing in the direction of its layering not completely by removing the layers of the package with sheet metal strips with resilient bulges, for example by means of spring tongue plates, between the package and the layers lying in the direction of lamination Housing inner walls are held tightly against one another.

Durch die Verwendung der elastischen Einlagen nach der Erfindung werden die sich unter Zwischenschaltung eines Separators gegenüberliegenden Elektrodenoberflächen mit über die ganze Oberfläche möglichst gleichmäßigem Abstand immer flächendicht aneinanderliegend gehalten. Die Saug- bzw. Kapillarwirkung des Separators kann bei jedem Betrieb des Akkumulators voll zur Auswirkung kommen, und es wird die Elektrolytflüssigkeit dadurch so zwischen den Elektrodenoberflächen ungleicher Polarität gespeichert Ständig gasdicht verschlossen zu betreibender alkalischer AkkumulatorBy using the elastic inserts according to the invention, the interposition of a separator opposite electrode surfaces with over the entire surface if possible always held tightly against each other at an even distance. The suction or capillary action the separator can come into full effect with every operation of the accumulator, and it the electrolyte liquid is thus stored between the electrode surfaces of unequal polarity Alkaline accumulator to be operated permanently sealed in a gastight manner

gehalten, daß der Ionenaustausch gewährleistet ist und auch jederzeit genügend Elektrolytflüssigkeit zwischen den dem Gasaustausch dienenden Elektrodenoberflächen vorhanden ist, um eine Lösung des an diesen Oberflächen entstehenden Gases in der Elektrolytflüssigkeit zwischen benachbarten Elektrodenoberflächen zu ermöglichen. Auch ist die Bildung von Kurzschlußbrücken zwischen Elektrodenoberflächen ungleicher Polarität dadurch vermieden, daß eine Beanspruchung der Separatoreinlagen durch hohen Preßdruck ausgeschlossen ist.kept that the ion exchange is guaranteed and always enough electrolyte fluid between the electrode surfaces serving for gas exchange is present in order to obtain a solution of the These surfaces arising gas in the electrolyte liquid between adjacent electrode surfaces to enable. There is also the formation of short-circuit bridges between electrode surfaces Unequal polarity is avoided in that the separator inserts are subjected to high pressure is excluded.

Beim Aufbau von Bleiakkumulatoren ist es bereits bekannt, zur Absteifung des Plattensatzes in den offenen Glasgefäßen sogenannte Endbleibügel zu verwenden, die in gleicher Weise wie Hartgummiendstäbe zwischen Gefäßwand und Plattensatz eingesetzt sind. Demgegenüber dienen die erfindungsgemäßen Blechstreifen mit federnden Ausbuchtungen dazu, dem flächendruckelastischen Elektroden - Separator - Paket eine flächenparallele Ausbuchtung bei ständigem Aneinanderliegen der Schichtoberflächen zu geben, woran bei der Benutzung der bekannten massiven, also nicht elastischen Bleibügel nicht gedacht ist.When building lead-acid batteries, it is already known to brace the plate set in the open glass vessels to use so-called end stirrups, which are made in the same way as hard rubber end rods are inserted between the vessel wall and the plate set. In contrast, serve the invention Sheet metal strips with resilient bulges in addition to the surface pressure elastic electrode separator package to give a bulge parallel to the surface with constant contact of the layer surfaces, on what when using the known massive, so non-elastic lead stirrups is not intended.

In der Zeichnung ist ein Beispiel der Erfindung dargestellt. An example of the invention is shown in the drawing.

Der Stahlblechstreifen 1 ist mit den Federzungen 2 versehen, die durch gleichzeitiges Stanzen und Drücken aus dem Material des Bleches 1 hergestellt sind. Dadurch, daß der Blechstreifen 1 solche Federzungen 2 über seine ganze Fläche verteilt aufweist, wird bei Einsetzen eines Stahlblechstreif ens I zwischen das Elektrodenpaket 3 und die Wandung 4 eines Akkumulatorengehäuses eine elastische Halterung des Paketes 3 in dem Gehäuse erreicht. Das Paket 3 wird unter einem weitgehend gleichmäßig über die Elektroden verteilten elastischen Anliegedruck der Schichtenoberflächen gehalten, was für den AufbauThe sheet steel strip 1 is provided with the spring tongues 2, which by simultaneous punching and Press from the material of the sheet 1 are made. The fact that the sheet metal strip 1 has such spring tongues 2 has distributed over its entire area, when a sheet steel strip I is inserted between the electrode package 3 and the wall 4 of a battery housing an elastic holder of the Reached package 3 in the housing. The package 3 is under a largely uniform over the electrodes distributed elastic contact pressure of the layer surfaces held, which is responsible for the structure
